To all whom it may concern.'

Be it known that I, JOHN J. Bowne, Jr.,

. a citizen of the United States, residing at Pensacola, in the countyof Escambia and State of Florida, have invented new and usefulImprovements in Hose-Couplings, of which the following is aspecification.

The invention relates to couplings, and more particularly to theclass ofhose couvplings,'the same being improvements on the constructiondisclosed in Letters Patent No. 699,366, issued to me on 'the 6th day ofMay, 1902.

The primary object of the invention is the provision of a hose couplingwherein the improved features thereof enable the proper seating of theresilient element for tension-- ing the displaceable locking sleevecarried by one of the members of t e coupling and also prevent therotation of the said sleeve relative to the parts supporting the samewhen in the act of joining or detaching the members of the coupling.

Another object of the inventionl is the provision of a coupling whereinthe coperating parts thereof are assembled in a unique manner so as topermit the easy and quick connection of the members of the coupling orthe detachment of the same from each other, the members when connectedwill Arender the coupling water-tight so as to avoid leakage, and alsosuch members can be automatically locked together in coupled position.

A further object of the invention is the provision of a coupling of thischaracter which is extremely simple in construction, thoroughly reliableand eiiicient in its purpose, readily and easily coupled and uncoupled,and also which is inexpensive in manufacture.

With these and other objects in view, the

' invention consists in the construction, combination and arrangement ofparts as will be hereinafter fully described, illustrated in theaccompanying drawing, and pointed out in the claim hereunto appended.

In the drawing :'-Figure 1 is a. side elevation of a hosecouplingconstructed in accordance with the invention, the members thereof beingcoupled. Fig. 2 is al vertical longitudinal sectional view of the same.Fig. 3 is a perspective view of the female member of the coupling. Fig.4 is a similar Amale member A for lookin view of the male member of thecoupling. Fig. 5 is a sectional view on the line 5-5 of girnilarreference characters indicate correspond'in parts throughout the severalviews in t e drawing.

Referring to the drawing in detail, A designates the female member ofthe coupling having an enlarged head 5 provided at dia metricallyopposite points with inwardly projecting substantially quadrantshapedflanges 6,. and in its'edges intermediate said flanges with recesses 7,and at a suitable distance in rear of said flanges to permit of theinsertion of lugs 8 behind the flanges 6 is an annular flange 9 formingan abutment wall for the lugs 8 when inserted in the feengagement withthe ilange's 6 on its hea This annu lar flange 9 also serves as a wallto a pocket 10 arranged rearwardly thereof and into which is fitted asubstantially U-shaped gasket or washer 11, the latter serving toprevent leakage when the female member A receives the male member B,which 'is herein after more fully described.

The male member B of the coupling is provided on its exterior with thesegmental lugs 8 which when said member is inserted inthe head; 5 byaslight twisting of either member is adapted to engage behind theflanges 6 andi thus secure the members against longitudinaldisplacement. The quadrant-shaped lugs 8 are preferably a little lessthan a quadrant to permit of their ready insertion between the ilange 9and the opposed flanges 6 of the head. The male member B is formed withannular shoulders 11 and 12 respectively, providing an annular recess 13therebetween, the said shoulders being located exteriorly of the memberB and have mounted thereon for longitudi nal movement a locking sleeveor ring 14 provided with. extensions 15 which are adapted to engage inthe recesses 7 in the head 5 to secure the members of the couplingagainst relative rotary movement and thereby, lock them againstaccidental uncoupling.

Located within the recess 13 and surrounding the male member B of thecoupling is an expansion spring 16 having one end resting against theshoulder 11', while the opposite end is adapted to rest against theinwardly bent terminals 17 and an opposite inward curvature 18respectively lof a split snap ring 19, the same being adapted to snapinto for locking engagement in an annular groove 2O formed in the innersurface of the locking sleeve or' ring 14, and in-this manner the saidspring 16 is properly seated against both the ring 19 and the shoulder11 so that the tension of the spring will be exerted against the sleeveor ring 14 for automatically shifting it to locking position.

- As heretofore stated, the gasket or washer 11 is approximatelyU-shaped in cross section and has the lips 21 thereof tapered. Thewasher 11 is carried within the head 5 in the pocket 10 therein, andwhen the members are coupled together as illustrated in Figs. 1 and 2 ofthe drawing the lips 21 spread, closing the space between the innerwalls of the head 5 and the outer surface of the member B. It will beapparent that from the above construction of the washer the Water willin passing through the coupling force the lips 21 apart and against thetwo members, and that the washer is held against displacement by theinner closed end o the head 5 and the flange 9 which retains the washerwithin the head ready to receive 30' the male member B of the coupling.

The shoulder 11" on the male member B of the coupling is formed with alongitudinally disposed guide channel or groove 22, while the sleeve orcollar 14 at the edge adjacent to the said shoulder is instruck toprovide a guide lip or projection 23 which is corre spondingly shaped'tothe groove or channel 22 for engagement therein. Thus, in this mannerthe sleeve or collar 14 is revented from relative rotation on the mem erB, yet permitting it to freely slide longitudinally thereon against theresistance of the spring 16 when coupling the members of lthe cou- Aanyof its advantages.

What is claimed is: A coupling comprising male and female members,spaced annular shoulders formed on the male member, a coiled springsurrounding the male member between the shoulders, a sleeve arrangedconcentricallyT with respect to the shoulder and slidably supportedthereby, the said sleeve being formed with an annular groeve in itsinner Y face,'a resilient split ring engaged in the said groove to forma seat for one end of the spring and also to serve as an abutment forone of the annular shoulders, the other shoulder being formed with agroove arranged longitudinally with respect to the male member, aninstruck lip formed on the sleeve and projected into` the last namedgroove for sliding movement therein, and means on the female member forreceiving a portion of the male member and having means for interlockingengagement with the same and the said'sleeve.

In testimony whereof I aiiix my signature in presence of two witnesses.
